Nautilus/Thunar file copy progress bar is not accurate.

https://bbs.archlinux.org – Hey Guys,I have posted this under 'Newbie Corner' because I'm really not sure where this should go. I am using Gnome 3.6 with GNOME Shell. When I copy a large file from one device to another (say, my SSD to a USB flash drive) I get the copy dialog box with the progress bar. This progress bar jumps to about 98%-99% and stays until the file is finished writing to the disk. So, basically, the progress indicator is useless for determining an ETA which is bothersome when copying large (or many) files. I see the same behavior with Thunar and Nautilus so I suspect the file manager is n (HowTos)
